Finding existing data
Research Data Management Support can help you find existing data to build upon.
The advantages of using existing data
Universities, research institutes, funders and publishers require you to make your research data as reusable as possible. This also makes it possible for you to use the data of others. Before you start your project, find out if the data you need is already available or if similar data exists. Then evaluate if the existing data is sufficient to conduct or complement your research with. It is worthwhile to use existing data for several reasons:
- It can inspire you to do other measurements.
- You can do a meta-analysis at the end of your project.
- You could save valuable time by not having to collect data and expand your research focus.
- Existing data can save you lots of time in optimising your specific study design or by simply reusing it.
